1. A three-dimensional (3D) display system for displaying a 3D image including a first view image and a second view image to a viewer, comprising: an arrangement module configured to alternatingly arrange a plurality of display units of the first view image and a plurality of display units of the second view image on a display panel; a processing module configured to obtain an information difference of a display unit of the second view image from display units of the first view image related to the display unit of the second view image, and re-calculate a pixel value of the display unit of the second view image; a displaying module configured to display to the viewer the display unit of the second view image with the re-calculated pixel value via a light separation device; and a first adjustment module configured to dynamically adjust a crosstalk intensity based on a viewer's position, wherein the crosstalk intensity increases or decreases with respect to a distance between the display units of the first view image and the viewer's position, wherein the processing module further includes: a first obtaining unit configured to obtain image information of the plurality of display units of the first view image; and a second obtaining unit configured to obtain crosstalk factors for the display units of the first view image with respect to the display unit of the second view image, wherein the information difference is related to the image information of the display units of the first view image and the crosstalk factors for the display units of the first view image with respect to the display unit of the second view image, and a sum of the crosstalk factors is related to the crosstalk intensity for the display unit of the second view image.
A 3D display system reduces crosstalk by alternating first-view and second-view image display units on a panel. It calculates the "information difference" (crosstalk) a second-view display unit receives from nearby first-view display units, and adjusts the second-view unit's pixel value to compensate. The displayed second-view image utilizes a light separation device. The system dynamically adjusts crosstalk intensity based on the viewer's position, with intensity changing relative to the distance between first-view units and the viewer. The system obtains image information from first-view display units and crosstalk factors representing their influence on the second-view unit. The information difference uses this image information and the crosstalk factors, and the sum of the crosstalk factors determines the crosstalk intensity.
2. The 3D display system according to claim 1 , wherein the display unit includes a pixel group, a pixel, or a sub-pixel.
The 3D display system described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image, defines a "display unit" as a pixel group, a single pixel, or a sub-pixel. So, the system can operate on groups of pixels, individual pixels, or even sub-pixel elements to correct crosstalk.
3. The 3D display system according to claim 1 , wherein the processing module further includes: a first calculation unit configured to remove the information difference, caused by the display units of the first view image to the display unit of the second view image, from the image information of the display unit of the second view image.
The 3D display system described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image, further includes removing the information difference (crosstalk contribution) from the first view image display units to the second view image display unit. The pixel value recalculation subtracts the crosstalk component from the original second-view pixel value.
4. The 3D display system according to claim 3 , wherein the processing module further includes: a second calculation unit configured to compensate the image information of the display unit of the second view image, wherein a compensation value is related to the image information of the display unit of the second view image, and the crosstalk intensity for the display unit of the second view image.
The 3D display system described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image by first removing a crosstalk component, then compensates the pixel information of the second view image. This compensation relies on a "compensation value" related to both the original pixel information of the second-view display unit and the calculated crosstalk intensity affecting that unit. This adjusts the pixel to restore brightness lost due to crosstalk removal.
5. The 3D display system according to claim 1 , further including: a second adjusting module configured to update the crosstalk intensity in real-time according to parallax between the first view image and the second view image, wherein the crosstalk intensity increases or decreases with respect to a first view parallax value and a second view parallax value.
The 3D display system described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image, also updates crosstalk intensity in real-time based on the parallax (image offset) between the first and second views. The crosstalk intensity increases or decreases based on the parallax values for both views. Larger parallax leads to more aggressive crosstalk reduction.
6. The 3D display system according to claim 1 , wherein the crosstalk intensity is calculated as the sum of the crosstalk factors caused by the display units of the first view image to the display unit of the second view image.
The 3D display system described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image, calculates the crosstalk intensity as the sum of individual "crosstalk factors." Each factor represents the crosstalk caused by a single first-view display unit on a particular second-view display unit.
7. The 3D display system according to claim 1 , wherein the crosstalk intensity is calculated as the sum of the crosstalk factors caused by certain display units of the first view image adjacent to the display unit of the second view image.
The 3D display system described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image, calculates the crosstalk intensity as the sum of crosstalk factors but only considers crosstalk from *adjacent* first-view display units, not all of them.
8. The 3D display system according to claim 1 , wherein the crosstalk factors are set as fixed values.
The 3D display system described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image, sets the "crosstalk factors" (the weight of the crosstalk from the first view) to pre-defined, fixed values. It does not measure or dynamically change them based on the current image being shown.
9. A method for reducing stereoscopic display crosstalk in a three-dimensional (3D) display system for displaying a 3D image including a first view image and a second view image to a viewer, the method comprising: alternatingly arranging display units of the first view image and display units of the second view image on a display panel; obtaining an information difference of a display unit of the second view image from the display units of the first view image, and re-calculating a pixel value of the display unit of the second view image; displaying to the viewer the display unit of the second view image with the re-calculated pixel value via a light separation device; and dynamically adjusting a crosstalk intensity based on a viewer's position, wherein the crosstalk intensity increases or decreases with respect to a distance between the display units of the first view image and the viewer's position, wherein obtaining an information difference further includes: obtaining image information of the display units of the first view image; and obtaining crosstalk factors for the display units of the first view image with respect to the display unit of the second view image, wherein the information difference is related to the image information of the display units of the first view image and the crosstalk factors for the display units of the first view image with respect to the display unit of the second view image, and a sum of the crosstalk factors is related to the crosstalk intensity for the display unit of the second view image.
A method for reducing crosstalk in a 3D display involves alternating first-view and second-view image display units on a panel. It calculates the "information difference" (crosstalk) a second-view display unit receives from nearby first-view display units, and adjusts the second-view unit's pixel value to compensate. The displayed second-view image utilizes a light separation device. The system dynamically adjusts crosstalk intensity based on the viewer's position, with intensity changing relative to the distance between first-view units and the viewer. Image information is gathered from first-view display units and crosstalk factors (their influence on the second-view unit) are obtained. The information difference uses this image information and the crosstalk factors, and the sum of the crosstalk factors determines the crosstalk intensity.

The crosstalk reduction method described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image, defines a "display unit" as a pixel group, a single pixel, or a sub-pixel. So, the method can operate on groups of pixels, individual pixels, or even sub-pixel elements to correct crosstalk.
11. The method according to claim 9 , wherein re-calculating a pixel value of the display unit of the second view image includes: removing the information difference, caused by the display units of the first view image to a display unit of the second view image, from the image information of the display unit of the second view image.
The crosstalk reduction method described previously, which reduces crosstalk by alternating first-view and second-view images on a panel, re-calculates a pixel value of the second view image by removing the information difference (crosstalk contribution) from the first view image display units to the second view image display unit. The pixel value recalculation subtracts the crosstalk component from the original second-view pixel value.
12. The method according to claim 11 , wherein re-calculating a pixel value of the display unit of the second view image includes: compensating the image information of the display unit of the second view image, wherein a compensation value is related to the image information of the display unit of the second view image, and the crosstalk intensity for the display unit of the second view image.
The crosstalk reduction method described previously, which reduces crosstalk by alternating first-view and second-view images on a panel, re-calculates the pixel value of the second view image by first removing a crosstalk component, then compensates the pixel information of the second view image. This compensation relies on a "compensation value" related to both the original pixel information of the second-view display unit and the calculated crosstalk intensity affecting that unit. This adjusts the pixel to restore brightness lost due to crosstalk removal.
13. The method according to claim 12 , further including: dynamically adjusting the crosstalk intensity in real-time according to parallax between the first view image and the second view image; wherein the crosstalk intensity increases or decreases with respect to a first view parallax value and a second view parallax value.
The crosstalk reduction method described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image, also updates crosstalk intensity in real-time based on the parallax (image offset) between the first and second views. The crosstalk intensity increases or decreases based on the parallax values for both views. Larger parallax leads to more aggressive crosstalk reduction.
14. The method according to claim 1 wherein the crosstalk intensity is calculated as the sum of the crosstalk factors caused by the display units of the first view image to the display unit of the second view image.
The crosstalk reduction method described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image, calculates the crosstalk intensity as the sum of individual "crosstalk factors." Each factor represents the crosstalk caused by a single first-view display unit on a particular second-view display unit.
15. The method according to claim 1 wherein the crosstalk intensity is calculated as the sum of the crosstalk factors caused by certain display units of the first view image adjacent to the display unit of the second view image.
The crosstalk reduction method described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image, calculates the crosstalk intensity as the sum of crosstalk factors but only considers crosstalk from *adjacent* first-view display units, not all of them.
16. The method according to claim 1 , wherein the crosstalk factors are set as fixed values.
The crosstalk reduction method described previously, which reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image, sets the "crosstalk factors" (the weight of the crosstalk from the first view) to pre-defined, fixed values. It does not measure or dynamically change them based on the current image being shown.
17. The 3D display system according to claim 1 , wherein: provided that I denotes a set containing all display units of the first view image that generate the crosstalk to the display unit of the second view image, and k and j are integers, the information difference caused by the display units R k,j of the first view image with respect to the display unit L k of the second view image is calculated by: ∑ R k , j ∈ I P k , j * R k , j wherein P k,j denotes the crosstalk factor for the display units R k,j of the first view image with respect to the display unit L k of the second view image.
The 3D display system described previously reduces crosstalk by alternating first-view and second-view images on a panel and adjusting pixel values of the second-view image. To compute the information difference (crosstalk) caused by the first view display units (R) to the second view display unit (L), it sums the product of the crosstalk factor (P) and the pixel value (R) for all first view units (Rk,j) that contribute crosstalk to the second view unit (Lk): `∑ R k , j ∈ I P k , j * R k , j`, where *I* is the set of all contributing first-view display units.
18. The 3D display system according to claim 17 , wherein: the pixel value of the display unit of the second view image is recalculated by: L k ′ = L k - ∑ R k , j ∈ I P k , j * R k , j wherein L′ k denotes the recalculated pixel value and L k denotes an original pixel value of the display unit of the second view image.
The 3D display system which reduces crosstalk by adjusting pixel values based on the contribution of the first view units to the second view units, calculates the new pixel value (L'k) of a second view display unit as the original pixel value (Lk) minus the sum of the crosstalk contributions. This calculation is performed as follows: `L k ′ = L k - ∑ R k , j ∈ I P k , j * R k , j`, where *L'k* is the recalculated pixel value, *Lk* is the original pixel value, *Pk,j* is the crosstalk factor, and *Rk,j* is the pixel value of the first view display unit. The summation includes all first-view units that contribute to the crosstalk on the second-view unit.
